Some armored buffaloes, radio pythons, and tigers whose roars can destroy trees are all blocked by guardrails made of machine gun towers.

But when there was a tenth of the distance from the crater, some eagles that could release the wind blade came to make trouble and attack.

Because it can fly, the guardrail made by the tower will be neutralized.

The cross firepower of the archer and the machine gun tower became the last line of defense. Under the premise that the two sides exchanged injuries, these mutant eagles did not have too strong armor and were wiped out.

But the closer you are to the crater, the more mutant beasts that can fly, and the desire to attack is strong, as if protecting the crater from being investigated.

But now Lin Fan has a lot of materials. He directly turned the guardrail of the machine gun tower into a thunder tower, forming a dense current wonder in the second half.

The Thunder Tower is an advanced tower branch of the energy tower, which can send powerful currents, bounce attacks on multiple targets, and paralyze the enemy.

If you change the angle, this Thunder Tower is very suitable for dealing with flying enemies.

A large number of flying mutant beasts are coming towards Lin Fan, the number may be tens of thousands.

There are flying snakes, flying mice, flying buffaloes, and even flying whales...

At this time, the Thunder Tower exerted a huge combat power. The electric current was conducted many times, and although it would become weaker, the powerful effect of the paralysis effect caused the flying mutant beasts to fall down one after another, gaining a lot of time.

Finally, with the assistance of the Thunder Tower, Lin Fan's guardrail was built to the crater, and the human investigation team can conduct sampling and analysis.

The result of the analysis is that this meteorite has the effect of allowing cells to evolve, and mankind has made breakthrough progress.

Sand Table World: Successfully complete the first puzzle in the second level. Since there were no casualties in the investigation team, the guardian tower was rewarded for the advanced branch...the tyrant tower.

The Tyrant Tower, as the name suggests, can hatch a tyrant in an hour.

One of the strongest melee ability as a single body.

Besides, Lin Fan also found a treasure under the crater.

This raised Lin Fan's material limit to 50,000.

Some maps may not have abundant materials.

The material limit determines the number of towers you can build.

Sand Table World: The second difficulty in the second level. Humans have received very powerful biochemical agents in the meteorites, and the surviving population in the city has been greatly improved. City A has broadcast to surrounding cities. A large number of people are migrating to City A. You have to build towers. Protect the safety of migrants.

From the perspective of God, Lin Fan found that the population of the three cities of BCD is coming here, but the journey is far, hundreds of kilometers, and the construction of towers along the way requires extremely large materials.

However, the monsters that attacked these migrants were also scattered.

To choose to build a tower, it is too wasteful of materials and time, although it has advantages for the subsequent expansion of other cities.

But it is not worth it at the moment.

Lin Fan built a large number of guard towers, first recruited fighters and archers, in batches, to protect the safety of the migrants along the way.

After upgrading the guardian tower to a tyrant tower, one tyrant will be hatched after one hour. Like the previous encounter, he wears a restraint and has a two-stage liberation form.

In City A, a gathering place has been established and is protected by guardrails, so you are not afraid of being attacked.

From the original 1,000 population, it rapidly increased to hundreds of thousands of people, and he is a survivor in City A.

The biochemical agent extracted from the meteorite has caused the population of City A to spring up like abilities after the rain. This is a benign stage.

Lin Fan can recruit blockers with the "Eagle Eye Technique". One handful of Barrett can block targets within 10,000 meters, which is especially effective for heavily armored units.

You can also recruit boxers with "unparalleled brute power", and the high-speed combo boxing method allows light armored enemies to be quickly cleared.

The recruitment ratio is one-tenth of the total population.

This greatly eased Lin Fan's manpower problems.

In addition to the necessary combat power to stay in the city, the rest of the blockers and boxers were sent by Lin Fan to meet the arrival of the migrants.

There will be a wave of plague on the migration route of City B, which is faster than crawlers, and once they are climbed up, there will be no bones left.

The survivors of City B have some protectors called arsonists. In order to survive the plague. The population is around 80,000.

However, the plague amount is more than one million.

The survivors in City B are racing against time. If they run past the plague, they will be able to escape. If they run, they will have no more bones left.

The name of the sonic rat in the plague is the pioneer, which can intercept the survivors first, and then the paralyzed rat, which can vomit a large amount of paralyzing fog, and make the trapped survivors lose resistance.

Then there is the Macrophages, which can gnaw off a corpse in minutes, and hundreds of thousands will come together. I am afraid that this 80,000 population is only a matter of seconds.

Because there is no particularly suitable method, Lin Fan can only send a "hero" fire mage of his choice to personally escort, and set up energy towers at the maximum interval as a protective measure.

The coverage of the energy tower is second only to the range of the artillery tower.

So it can cover a large area.

A lightly armored enemy like the Plague, whose body shape means that the vitality is unlikely to be too strong, so when it rushes into the energy tower to attack the human migration team, it has been killed by the energy tower's radiation.

With the protection of the arsonists of the migration team, Lin Fan's fire mage, and some warriors and archers, for the time being, it is foolproof.

The migration route of City C needs to cross a river port, but there are many aquatic mutants below. Common carps have mutated into carnivores and reproduce very quickly. Without protective measures, even the tyrant will fall. No bones exist.

However, Lin Fan built the Thunder Tower on the ship, and the water can conduct electricity. Only the Thunder Tower is needed here, which is safer than other routes, as long as the migration team does not fall into the river.

The troops owned by City C are blasters and technicians who install explosives, which are of great use in certain situations.

Next is the most difficult city D. The troops in this city are a group of mechanics who can create and control two mechanical dogs at the maximum, but the route they need to take is next to the forest, which may easily trigger a beast attack.
